Suppose you have to determine the percentage of carbon dioxide in a sample of a gas available in a container. Which is the best absorbing material for the carbon dioxide
1 Heated copper oxide
2 Cold, solid calcium chloride
3 Cold, solid calcium hydroxide
4 Heated charcoal
Explanation:
(c) \(C{O_2}\) is acidic oxide and thus more effectively absorbed by an alkali.
